Title:

作動の終了の瞬間を検出する電気アクチュエータの制御装置、および電気アクチュエータ作動の終了の瞬間を検出する方法

Document Type and Number:

Japanese Patent JP4332100

Kind Code:

B2

Abstract:

A description is provided of a device (2) for control of an electro-actuator (3), comprising a first and a second input terminal (4,5) which are connected to an electrical energy source (6); and a first and a second output terminal (10,11) which are connected to the electro-actuator (3). The control device (2) additionally comprises a threshold comparator (30) which can compare the voltage (VHS,VLS) present at the first or second output terminal (10,11) of the control device (2) with a threshold voltage (VTH_EOI) and can generate a signal (VEOI) which is indicative of the instant of end of actuation of the electro-actuator, when this voltage (VHS,VLS) passes through the threshold voltage (VTH_EOI).
